To all whom) it may concern:

Be it known that we, PHILIP MUELLER, ANTON C. SOHUERMANN, and ROBERT H.

MUELLER, citizens of the United States, re-' siding at Decatur, in. the county of Macon- .for flanging lead pipe to adapt itfor connecport placed in or across the ditch containing;

tion in union lead flange couplings such as are employed in connecting water supply mains with house service pipes.

The object of the invention is to provide a simple and durable apparatus for the purpose described which may be operated in.

either a vertical or horizontal position and be readily attached to a board or other supthe. service. pipe.

' More especially, the subject matter of the present application is an improvement upon the apparatus shown in a co-(pending case of Philip Mueller and 1\I%1)ton Schuermann, filed November'12, 191 Serial No. 337,498,

the present construction being less expensive than that of the application referred to.

and

F 1 in-wl iich pipes flanged by the ferredto may be em loyed.

Referring to the rawings, the apparatus apparatus re comprises the main frame, shown as a U-'. shaped casting, 1 which .has, one limb adapted to be detachably but securel fastened' to a. base 2 which in turn is a apted to'be secured to a board or other sup-port 3 as by means of bolts 4. Alined bores are formed in the end members of the frame 1, and one of said members is provided vwith Specification of Letters Patent. Application filed December MACHINE FOR FLANG-INE SOFT-METAL PIPES.

the depending flange 1 which is secured to the base 2 by suitable screws 5.. Asshown in Figs. 1 filo-3, the main frame casting 1 is arranged 1n a horizontal position, the lip or-flange 1 extending vertically and bearing against a vertical face of the base 2. Said Within the bore formed in the main frame 1 adjacent the base 2 is arranged a sectional bushing constituting the pipe clamp. As shown, this bushing comp-rises two generally sim lar sections 6, 7, each being-provided at one end'w'ith notched projections adapted to engageco-rresponding lugs 1 on the main frame so that the bushing will be'properly positioned within the bore in the frame 1 and the bushing member 7 is provided witha recess 7 a adapted to receive the inner end of'afasteningscrew 8 by means of' which pressure can be exerted to. cause the two 4 bushing sections to firmly grasp the pipe 10.

to be flanged. A suitable socket 12 is formed at one end of the sectional bushing to receive a coupling member or tail piece? 13 against WhlCh the end ofthe tube 10f-1s adapted to be flanged.

finger being held in position on the pinv by a nut 16 and said stop is adapted to'be turnedso that its end will-project more or less acrossthe passage through the bushings 6, 7 whereby it will act'to limit movement of the machine.

Within the bore formed in the other, limb of. the *U-shaped frame 1 is fitted an interio-rly threaded bushing20, held in place by anut 21 and through said bushing is adapted to work a feed screw 22, having its inner end reduced and pointed, as at 23.

- The Hanging tool comprises a head 25 havng a tapering centering projection 26 and a plurality of flangin projections 27, said centering rojection eing adapted to extend intoa t e tube to be operated on to-pre vent crushing of-the walls thereof duringthe flanging operation. A trimmer or cutter 28 is mounted in the head 25, being held in the desired adjusted'relationthereto by a suitable screw 29. The shank 25" of the 85 stop finger-14: is pivotally 'mounted on a pin 15. projecting from the frame 1, said Hanging tool is. held in a suitable socket formed at one end of a tool holder 30, as by a set screw 25a, and with said holder 30 is adapted to cooperate a suitable lever 31 and ratchet wheel 32 by means of which the Hanging and trimming tool may be rotated. At one end the tool holder 30 is provided with a recess toreceive. the reduced tapered end 23 of the feed screw 22.

It will be understood that the machine described is adapted for Hanging pipe of any size, it merely being necessary to makebushings 6, 7 of the requiredthickness and to have the parts of the Hanging tool properlv proportioned.

To use the apparatus. the feed screw 22 will be turned to withdraw the. pointed end thereof into the bushing 20, the Hanging tool and means for rotating the same being removed from the frame. The. lock screw 8 being suitably withdrawn.- the pipe 10 to be Hanged having placed, thereon the sleeve or coupling 13 and the appropriate bushings 6, 7, is inserted in the frame and the lock screw actuated to clamp the parts therein. The

extent to which the tube or pipe projects from the sleeve 13 is determined by the stop 14, which is turned to constitute an abutment; and sleeves of different lengths may be employed according to the extent which is desired to flange the tube. The clamps or jaws 6, 7 will be held from turning by the en agement of the lugs or pins 1 therewith.

he centering projection 26 is then inserted in the end of the tube of pipe 10 and the feed screw 22 actuated to bring the pointed end thereof into the socket provided for it in the end of the tool holder. Further actuation of the screw 22 will move the centering projection 25 into the tube and cause the Hanging projections 27 thereon to flange one end of the tube against the.sleeve 13. By means ofthe lever 31 and ratchet 32 the Hanging tool will be given a continuous rotating movement, the end of the pipe flanged down and the cutter 28 thereof caused to trim the periphery of the flange. After the flange has been thus formed and trimmed the feed screw is retracted from the holder and the latter removed from the apparatus after which, by loosening the screw 8 the bushings 6, 7, and Hanged pipe may be readily withdrawn through the bore in the frame 1, said bushings, of course, being easily removed from the pipe when it has been thus withdrawn.

As shown in Fig. 7, a lead pipe flanged as thus descrlbed is adapted to be connected with a main 40 by means of a. suitable coupling sleeve 41.
